With this version, this is the part of the log after a Max mains was exceeded for a very short period of time. Then after one minute, the EVSE tried to re-initiate the charging session but after activating the contactor, screen went blank, contactor switched off,

Ok that's funny I just fixed that bug, see #24 , bottom of the discussion the "1eeb20ba03+1.zip" should fix it...

[mintgroen]

Flashed that version, triggered the symptom by exceeding max mains and the same behavior occurs.

Kona stops the charging, after 60 seconds the EVSE tries to restart the charing, state C but after the contactor close, it reopens again. see line 619 and further of the telnet log:

log.txt

I can't see anything strange in those logs; I understand v3.0.1 worked, the easiest way to find this problem is to move through history and narrow it down to the commit that introduced the problem. So first flash v1.8.0 , if it works then, goto v3.5.0-RC0, but if it doesn't, go back to v1.6.0 or even v1.4.4 ; that's the nice thing about this repo, you can go all the way back to the first commit, which is Stegen's v3.0.1 .

The binaries of v1.8.0 and earlier you can pull off the serkri repo, but it is pretty simple to compile yourself: https://github.com/dingo35/SmartEVSE-3.5/blob/master/docs/configuration.md see bottom of page.

If you can find the disturbing commit I'm happy to work around it. The alternative is that you park your Kona at my house for a few weeks :-) .

@mintgroen Could you please test if this version still has problems with the Kona?

[mintgroen]

Sure will do, the sun was shining so the Kona is full atm. I'll test asap.

[mintgroen]

Did some testing and the Kona seems to listen to the EVSE and restarts charging when the power availability returns.

Thanks!
